Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and more specifically, to a push-pull rod folding plate transport device that can move in a curved path. Background Technology

[0002] Massage sofas typically have grooves in the backrest to accommodate the massage mechanism. However, when a person sits on the sofa, the backrest sags, compromising the sofa's comfort. To improve both comfort and massage functionality, a support mechanism is needed to support the body when not massaging, enhancing the sofa's seating comfort. This mechanism needs to be concealed during massage operations. Utility Model Content

[0003] This invention overcomes the shortcomings of the prior art and proposes a push-pull rod folding plate transport device that can move along curves. Its structure is reasonably designed. The linear movement of the transmission shaft can be converted into curved movement through the swing rod, so that the support plate can move along both straight lines and curves, thereby achieving the purpose of hiding the support plate and supporting the human body.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A push-pull rod folding plate transport device capable of curved movement includes a drive assembly, a swing rod, and at least one support plate. The swing rod includes a guide end and a hinge end. The guide end is rotatably connected to a drive shaft, and the hinge end is rotatably connected to the support plate. The drive shaft is driven by the drive assembly and moves along a straight line, while the support plate is driven by the swing rod and can move along a curve.

[0005] By adopting the above technical solution, a bushing can be fixed on the drive shaft, the guide end of the swing arm is rotatably sleeved on the bushing, and the hinge end of the swing arm is rotatably mounted on the support plate. The swing arm pushes and pulls the support plate, converting the linear movement of the drive shaft into curved movement, allowing the support plate to move along both straight and curved lines. Thus, when the support plate moves along a curved line, it is concealed. When the support plate moves in a straight line or reaches the junction of a curved and straight line, it provides support for the user's lower back, as it is used in a massage sofa. This achieves an effect that neither affects the massage experience nor the comfort level.

[0006] Preferably, the drive component includes a synchronous belt structure, and the conveyor belt of the synchronous belt structure is set in a straight line.

[0007] By adopting the above technical solution and using a synchronous belt structure for transmission, the structure is simple in design, the transmission is smooth, and the transmission belt is set flat, which can ensure the smoothness and accuracy of the linear movement of the transmission shaft.

[0008] Preferably, the conveyor belt is provided with a fixed seat, which is fixedly connected to the drive shaft, and also includes a limiting component for limiting the movement distance of the fixed seat. The limiting component includes a Hall sensor located on one side of the conveyor belt and a magnet disposed on the fixed seat.

[0009] By adopting the above technical solution, the fixed seat is fixedly installed on the transmission belt. As the transmission belt moves, the transmission shaft is fixed to the fixed seat, thereby driving the transmission shaft to move in a straight line. The limiting component limits the movement of the fixed seat, preventing excessive movement of the transmission shaft. Specifically, the limiting component uses a magnet and a Hall sensor, where the Hall sensor is located on one side of the transmission belt rather than being fixed to the belt. Of course, a direct contact limiting solution can also be used, such as a limiting block with a buffer pad.

[0010] Preferably, the drive assembly further includes a drive unit and a drive shaft that drives the synchronous belt structure transmission, the drive shaft being driven by the drive unit.

[0011] By adopting the above technical solution, two synchronous belt structures are set up, and the two synchronous belt structures are connected by a drive shaft. The synchronous belt can be moved by driving the shaft to rotate through the drive unit. Specifically, the drive unit can adopt a geared motor and pulley scheme, or other existing mature technologies that can realize forward and reverse rotation of the drive shaft can be used.

[0012] Preferably, there are multiple support plates, and the multiple support plates are hinged together.

[0013] By adopting the above technical solution, the arrangement of multiple support plates provides better support for the human body. Considering that the support plates need to bend and move, the multiple support plates are hinged together, allowing each support plate to bend at a certain angle, thus ensuring that all support plates can move in a curved path.

[0014] Preferably, the support plate is provided with a connecting seat, the connecting seat is provided with a guide post, and the connecting seat is formed with a receiving groove for accommodating the swing arm, and the hinge end is hinged in the receiving groove.

[0015] By adopting the above technical solution, the connecting seat can be integrally injection molded with the support plate, or it can be a sheet metal part and fixedly connected to the support plate, as long as the connecting seat can meet the requirement of having a certain strength.

[0018] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] It should be noted that all directional indicators (such as up, down, forward, backward, etc.) in the description of this utility model are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] like Figure 1-9 As shown, a push-pull rod folding plate transport device that can move along a curve includes a drive assembly 4, a swing rod 5, and at least one support plate 6. The swing rod 5 includes a guide end 51 and a hinge end 52. The guide end 51 is rotatably connected to a drive shaft 7, and the hinge end 52 is rotatably connected to the support plate 6. The drive shaft 7 is driven by the drive assembly 4 and moves along a straight line. The support plate 6 is driven by the swing rod 5 and can move along a curve.

[0023] By adopting the above technical solution, specifically, a bushing can be fixed on the transmission shaft 7, the guide end 51 of the swing arm 5 is rotatably sleeved on the bushing, and the hinge end 52 of the swing arm 5 is rotatably mounted on the support plate 6. The swing arm 5 will push and pull the support plate 6, and the linear movement of the transmission shaft 7 can be converted into curved movement through the swing arm 5, so that the support plate 6 can move along both straight lines and curves. In this way, when the support plate 6 moves along a curve, it can be hidden. When the support plate 6 moves in a straight line or moves to the junction of the curve and the straight line, since the support plate 6 is used in the massage sofa, it can support the lower back of the human body. Thus, the effect of neither affecting the massage nor the comfort is achieved.

[0024] Furthermore, the drive assembly 4 includes a synchronous belt structure 41, with the transmission belt 42 of the synchronous belt structure 41 being straight. Using the synchronous belt structure 41 for transmission results in a simple structural design, smooth transmission, and the straight transmission belt ensures smooth and accurate linear movement of the drive shaft 7.

[0025] Furthermore, a fixed seat 43 is provided on the conveyor belt 42, which is fixedly connected to the drive shaft 7. A limiting component 9 is also included to limit the movement distance of the fixed seat 43. The limiting component 9 includes a Hall sensor 92 located on one side of the conveyor belt 42 and a magnet 91 disposed on the fixed seat 43. The fixed seat 43 is fixedly installed on the drive belt. As the drive belt moves, the drive shaft 7 is fixed to the fixed seat 43, thereby driving the drive shaft 7 to move in a straight line. The limiting component 9 limits the movement of the fixed seat 43 to prevent excessive movement of the drive shaft 7. Specifically, the limiting component 9 uses a magnet 91 and a Hall sensor 92, where the Hall sensor 92 is located on one side of the drive belt rather than fixed to the conveyor belt 42. Of course, a direct contact limiting scheme can also be used, such as a limiting block scheme with a buffer pad.

[0026] The drive assembly 4 also includes a drive unit 44 and a drive shaft 45 that drives the synchronous belt structure 41. The drive shaft 45 is driven by the drive unit 44. Two synchronous belt structures 41 are provided and connected to each other by the drive shaft 45. The synchronous belt can be moved by rotating the drive shaft 45 driven by the drive unit 44. Specifically, the drive unit 44 can adopt a geared motor and pulley scheme, or other existing mature technologies that can realize the forward and reverse rotation of the drive shaft 45 can be used.

[0027] In addition, multiple support plates 6 are provided, and the multiple support plates 6 are hinged together. The arrangement of multiple support plates 6 provides better support for the human body. Considering that the support plates 6 need to bend and move, the multiple support plates 6 are hinged together, so that each support plate 6 can bend at a certain angle, thereby ensuring that the multiple support plates 6 can achieve curved movement.

[0028] Furthermore, a connecting seat 61 is provided on the support plate 6, and a guide post 62 is provided on the connecting seat 61. A receiving groove 63 for accommodating the swing arm 5 is formed on the connecting seat 61, and the hinge end 52 is hinged in the receiving groove 63. The connecting seat 61 can be integrally injection molded with the support plate 6, or it can be a sheet metal part and fixedly connected to the support plate 6, as long as the connecting seat 61 can meet certain strength requirements.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
